IMPROVEMENT IN TINSMITHS FIRE-POTS.

Specification forming part of Letters Patent No. 39,52l, dated August11, 1863.

. part of this specification, in which- Figure 1 is a perspective viewof the firepot. Fig. 2 is a front view. Fig. 3 is a side view. Fig. 4 isa vertical section through the fire-pot from side to side. Fig. 5 is avertical section of the samefrom front to rear.

The nature of my invention consists in an improved combination andarrangement of parts whereby the heating of the solderingcoppers may bemore readily and economically effected, the apparatus more easilysupplied with fuel, its heat regulated and controlled, and meansprovided'for placing the copper directly in the fire when it is to beforged to a point.

In order that others skilled in the art to which myinvention appertainsmay be enabled to fully understand and use the same, I will proceed todescribe its construction and operation.

A A represent horizontal cylinders, of which there may be one, two, ormore, extending longitudinally through a rectangular box or casing, A,from end toend. Under these cylinders is placed the grate B, Figs. 4 and5, leaving a space between the cylinders and the grate where the coallies, as represented in Figs. 4 and 5. The coal is put into the firepotthrough an opening, 0, Fig. 4:, on the side, which is closed up again bya door, D, Figs. 1, 2, 3, and 4. In the top of the fire pot I leave anopening, F, Figs. 1, 4, and 5, provided with a collar, G, Figs. 1, 2, 3,4, and 5, the same as is put onto any common stove to allow of astove-pipe being put onto it for the escape of the smoke from the fireand to create a strong draft. I also provide the stovepipe with adamper, such as are commonly used on ordinary stove-pipes to regulatethe draft. By these means after the fire has been kindled a great heatcan be obtained, and the Q cylinders A thoroughly heated by opening alittle the ash-box K. After the cylinders have become sufficientlyheated the heat may be kept in the fire-pot by keeping the opening E,Fig. 5, closed by the door H, Figs. 1 and 2. Below the grate B is placedthe ash-box K, made the same as in any ordinary stove. I also put theopening E, Fig. 5, in the front of the fire-pot, which can be keptclosed by the sliding door H, Figs. 1 and 2, which will move in theslide-ways J, Figs. 1, 2, 3, and 5. The opening E is placed there toallow the soldering-copper to be put into the fire when necessary toforge it to a point. It will be clearly seen and understood that as thecylinders A are located in the, center and pass entirely through thelength of the fire-pot, the burning coal and the fire surrounding themmust make the cylinders red-hot and consequently create an intense heatinside of them. In these cylinders now I place the soldering-copper L,as shown by Fig. 5, Where it will be perfectly heated to use it forsoldering.

The advantages gained by heating the soldering-copper in this manner arethe followin g The soldering-copper, not coming into contact with thefire itself, is kept free from smoke and sulphur caused by the burningof coal, which thus will not destroy the adhesive portion of sold er,which mustbe on asoldering copper and which is commonly called the face.This is a great saving of tools. The solderingcopper is also protectedfrom getting overheated, which is also a reason for not destroying theadhesive portion of solder, whereas, on the other hand, when thesoldering-copper is put into the fire itself, this adhesive portion willbe destroyed when the same is getting overheated. Another advantage isalso that, in this manner of heating the soldering-copper the same isalways kept clean and ready for use. Furthermore, any kind of coal,whether anthracite or bituminous, may be burnt in this fire-pot. It is awell-established fact that this coal gives a greater heat and holds onlonger than charcoal, which can only be used in the fire-pots at presentin most common use. This is also a great saving of fuel, for a halfbushel of hard or soft coal will burn longer and give more heat than onebushel of charcoal. In addition I wish to say that the firepotthroughout is intended to be made of castiron, and that the cylinderscan be made separate and placed a small distance apart from each other.The cylinders can be taken out when burnt and be replaced by new ones.

By applying a register or door of any suitable form to the back of thefurnace the rear ends of the tubes may be opened at will, to cause acirculation of air whenever it may be needful to cool the tubes, inconsequence of their havin g become overheated.

I am aware thatfurnaces have before been devised for heatingsoldering-coppers within tubes, so as to protect them from directcontact with the fire, and therefore do not desire to be understood asclaiming this invention, broadly; but,

Having thus described my invention, what I claim as new herein, anddesire to secure by Letters Patent, is I The combination, with therectangular box or casing A, of one or more longitudinal cylinders, A,grate B, openingsO E, doors D H, and sliding drawer K, all arranged asand for the purposes specified, and adapted for completely preventingcirculation of air when required.
